The Lewin Group, Inc.

The Lewin Group, Inc., doing business as Lewing Group Inc., is a healthcare and human services consulting subsidiary of UnitedHealth Group (parent: Optuminsight, Inc.) that delivers health policy research, claims analytics, program evaluation, and evidence-building services to federal health agencies as a prime contractor competing in full and open competition without set-asides. Headquartered in La Crosse, Wisconsin, with primary work locations in Falls Church, Virginia and Windsor Mill/Milford Mill, Maryland, The Lewin Group operates predominantly as a prime (99% of awards) with minimal subcontract exposure.

Customer concentration is severe and reflects The Lewin Group's positioning as a specialized federal health consultant. The Centers for Medicare and Medicaid Services dominates both award count and dollar value, accounting for 100 awards with combined potential value of $5.26 billion—71% of the vendor's total $7.36 billion portfolio. The Department of Health and Human Services Office of the Assistant Secretary for Administration ranks second with 74 awards and $909.3 million combined potential value. These two HHS entities account for 45% of award count and 95% of combined potential value across all customers. The Health Resources and Services Administration, Food and Drug Administration, and Department of Veterans Affairs round out the active set, but all other agencies combined represent less than 5% of dollars. The Lewin Group has worked with 44 distinct customer agencies, but concentration at CMS and HHS administrative functions is unmistakable.

The Lewin Group holds seat on multiple high-value parent vehicles anchoring federal health work. The CMS Research, Measurement, Assessment, Design, and Analysis (RMADA) 2 IDIQ has generated 17 task orders with combined potential value of $352.8 million for work including States Advancing Ahead Model implementation ($143.3 million ceiling), Long-Term Enhanced program support ($127 million ceiling), Advancing Chronic Care and Effective, Scalable Solutions (ACCESS) model implementation and monitoring ($79.1 million ceiling), and GUIDE Model implementation and monitoring ($74.9 million ceiling). A successor RMADA 3 IDIQ was awarded July 9, 2026, with a $3.5 billion ceiling running through July 8, 2031, positioning the vendor for long-term delivery of analytic support across CMS innovation programs. The Lewin Group also holds a $344.7 million single-award IDIQ from the Health Resources and Services Administration for evidence building and evaluation services (awarded September 26, 2024, through September 25, 2027), a $75 million multiple-award IDIQ from the Food and Drug Administration's Center for Biologics Evaluation and Research for health care data sources for surveillance of biologics (awarded September 26, 2024, through September 29, 2029), a $75 million multiple-award IDIQ from the Administration for Community Living (awarded January 22, 2024, through January 21, 2029), and placement on the GSA Multiple Award Schedule with 52 task orders generating $147.6 million in combined potential value. A single-award SAMHSA IDIQ carries a $1,000 ceiling.

Recent task-order activity demonstrates strong CMS pipeline momentum. The Lewin Group received a $127 million delivery order on April 24, 2026, for technical and operational support of the Long-Term Enhanced program under RMADA 2 (ultimate completion June 17, 2036), a $79.1 million order on April 1, 2026, for ACCESS model implementation and monitoring (ultimate completion March 31, 2036), a $7.85 million delivery order on September 30, 2026, for health care data sources for surveillance of biologics under the FDA CBER BEST Initiative 3 IDIQ (ultimate completion September 29, 2027), and a $21 million delivery order on September 6, 2024, from CMS for consolidated learning systems supporting model implementation and monitoring (ultimate completion September 5, 2029). On the civilian benefits side, The Lewin Group received a $5.73 million delivery order on June 1, 2026, from the Centers for Medicare and Medicaid Services under the GSA Multiple Award Schedule to produce improper payment rates for Federal Exchange Improper Payment Measurement and State-Based Exchanges Improper Payment Measurement programs for benefit years 2026–2029 (ultimate completion December 31, 2030, firm fixed price).

Service Contract Inventory data shows steady federal services delivery. SCI-reported invoicing across prime contracts reached $266.4 million from fiscal 2022 through fiscal 2025, with $63 million invoiced in FY2022 (210 FTEs), $65.2 million in FY2023 (185 FTEs), $65.6 million in FY2024 (186 FTEs), and $72.6 million in FY2025 (183 FTEs), reflecting stable to modestly rising invoicing on a consistent labor footprint. Across SCI-reportable prime contracts, The Lewin Group derives a median government-paid hourly rate of $164.22 per hour, with the 10th percentile at $0.00 per hour (likely representing early-phase or zero-invoicing contracts) and the 90th percentile at $355.89 per hour, indicating senior-level management and specialized expertise commands premium rates. The GSA Schedule labor portfolio spans eight categories from Executive Project Assistant at $107.56 per hour (high school education, five years experience) through Senior Vice President at $388.41 per hour (bachelor's degree, seventeen years experience), with no security-cleared positions offered—consistent with the vendor's civilian health-agency customer base and non-classified work scope.

Subcontracting depth across SCI-reportable prime contracts averages 16 percent of contractor hours performed by named subcontractors, with 107 total named subcontractors reported. The subcontracting posture signals The Lewin Group builds substantial internal delivery capacity while engaging specialists on defined tasks. On individual contracts, subcontracting varies: the GUIDE Model contract deployed 36 percent subcontract hours in fiscal 2025 to one subcontractor; the Maryland Total Cost of Care and Vermont All-Payer Models contract reached 10 percent subcontract hours across three subcontractors in fiscal 2025; the Enhancing Oncology Care Model contract subcontracted 27 percent of hours to one subcontractor in fiscal 2024; the Pennsylvania Rural Health Model and several smaller orders show zero subcontract engagement.

Award activity trajectory shows moderation over the past two years. The vendor received seven prime awards in fiscal 2022, eight in fiscal 2023, twelve in fiscal 2024, one in fiscal 2025, and five in fiscal 2026 year-to-date. The drop in FY2025 likely reflects the timing of large IDIQ awards in 2024 and the ramp of multi-year task orders under existing vehicles rather than new procurement launches. Awards with ultimate completion in the next twenty-four months total nine with combined potential value of $82.2 million, representing a modest recompete exposure window—much of The Lewin Group's dollar value is locked into long-term delivery orders extending through 2034–2036.

In its sub role, The Lewin Group provides implementation and monitoring support to National Opinion Research Center on the Transforming Maternal Health Model under a December 6, 2024 delivery order. The vendor has reported minimal subcontract activity (four sub awards in the full portfolio, 1% of total), indicating it operates predominantly as a prime.

The Lewin Group competes in full and open competition across its entire prime footprint with no set-aside designations, positioning it against large integrated consulting firms and specialized healthcare research contractors. The vendor's capability portfolio centers on research design, program evaluation, healthcare data analytics, policy analysis, and technical assistance for Medicare and Medicaid models and innovation initiatives. NAICS distribution reflects this focus: 202 awards fall under Administrative Management and General Management Consulting Services; 68 under Research and Development in the Social Sciences and Humanities; and 34 under Other Management Consulting Services. PSC codes emphasize Support-Professional-Other (109 awards), Support-Management-Other (61 awards), and Health R&D Services and Applied Research (50 awards).
